The Dallas-Fort Worth-Arlington metropolitan area’s 146,000-resident jump in 2017 was the most of any metro area in the United States. And six of the top 10 fastest-growing counties in the United States were also in Texas, including Tarrant, Dallas, Denton and Collin.

"In some ways, it continues the story we've been telling that we continue to see substantial growth in urbanized areas in that population triangle between Dallas-Fort Worth, San Antonio-Austin and Houston," said state demographer Lloyd Potter of the University of Texas at San Antonio.
